please get some header advice 67 dart gt

hello i am having trouble with some headers i have they will not fit the power steering is in the way there cheap no name set i was told will fit with ps but they will not .had engine foot in the air banged with sledge hammer cannot get to sit flat due to ps so i assume there manual steering headers.so i am in need of some headers that will fit.i have a 67 dart with a 73 scamp k frame with a 318 with power steering.i really do not want stock manifolds please suggestions on what will fit.thank you
I will only install a good header anymore in a A-body. I've done the cyclones, hedmans, etc, and not interested in doing any of those in a A-body anymore. I've had great experience with Doug's, I haven't tried TTI headers but I have run their 2.5" head pipes with manifolds and they fit like a glove.
